GCTS Testing Systems

What GCTS Testing Systems does

GCTS Testing Systems is a privately held, US-based manufacturer of advanced material testing equipment for geotechnical and pavement engineering applications. Founded in 1994 and headquartered in Tempe, Arizona, the company designs and builds turn-key testing systems and accessories for characterizing the mechanical properties of rock, soil, asphalt, and concrete. Its product portfolio spans dedicated hardware lines (RTR for rock, STX for soil, asphalt/concrete testers such as AMPT-15, ADM-100, APT-100, BFF, IDT, and SPAX true-triaxial systems) and a software/electronics platform comprising the CATS Testing Software for data acquisition and control and the gTest Mobile Application for iOS, Android, and Windows devices. Differentiated hardware innovations include the SRC-100 Resonant Column Device (with laser-sensor angular deformation measurement and spring-suspended torque motor), the ePVC Series standalone pressure/volume controllers requiring no external hydraulic or pneumatic supply, and the Balanced Mix Design Tester with 24-bit resolution and 1000 Hz sampling. The CATS/gTest stack functions as a platform hub tying load frames, sensors, controllers, and the new Environmental Chamber into an integrated testing ecosystem.

GCTS serves four primary customer verticals: Research & Academia (universities and research institutions), Construction & Civil Engineering (firms requiring materials QA/QC for infrastructure projects), the Energy Sector (oil & gas operators conducting core analysis, reservoir characterization, and high-pressure/high-temperature coreflooding), and Mining (rock mechanics and abrasiveness testing). Named customers include Petrobras, Rice University, Arizona State University, and Satbayev University in Kazakhstan. The company has delivered more than 1,000 testing systems to customers in over 70 countries.

The business model combines hardware sales (turn-key testing systems and accessories) with professional services (on-site installation, system calibration, operator training, and ongoing technical support). GCTS goes to market through direct field sales supplemented by a network of local distributors worldwide, supported by participation in industry conferences and trade shows. Pricing is quote-based with no public list prices. The company maintains ISO 9001:2015 certification, is founder-owned, has not disclosed external funding, and operates with a small employee base of 11-50, indicating a focused, profitable niche industrial OEM rather than a venture-backed growth company.

Core offering

GCTS Testing Systems manufactures and sells turn-key material testing systems and accessories for rock, soil, asphalt, and concrete geotechnical applications, including load frames, triaxial cells, pressure/volume controllers, resonant column devices, and environmental chambers. The company complements its hardware with proprietary CATS Testing Software for data acquisition and control and the gTest Mobile Application for iOS, Android, and Windows devices. Revenue is generated primarily through equipment sales and ancillary professional services such as on-site installation, calibration, operator training, and ongoing technical support.

Product overview

GCTS Testing Systems is a manufacturer of material testing equipment for geotechnical and pavement engineering applications. The product portfolio is organized around a platform-plus-modules architecture, centered on CATS Testing Software (the core control and data collection platform) and gTest Mobile Application (for mobile control and monitoring). The hardware lineup spans multiple specialized product lines: RTR Series for rock testing, STX Series for soil testing, and a comprehensive range of Asphalt/Concrete/Universal testing equipment including the AMPT-15, ADM-100, and APT-100 dynamic modulus testers, BFF flexural fatigue systems, IDT indirect tension testers, and various supporting accessories such as environmental chambers (ECH Series), pressure/volume controllers (ePVC Series), resonant column devices (SRC-100), and data acquisition systems (DataCube). Together, these products enable engineers to evaluate the mechanical properties of rock, soil, asphalt, and concrete materials across a wide range of test protocols.
